10、e WTSC Resolution No. 1 procedure on the 1st of July 1996. - STD-ITU-T RECMN D-233-ENGL 1776 W 48b257L Ob23072 7TT = FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (IW-
11、T) is a permanent organ of the ITU. Some 179 member countries, 84 telecom operating entities, 145 scientific and industrial organizations and 38 international organizations participate in ITU-T which is the body which sets world telecommunications standards (Recommendations). The approval of Recomme
12、ndations by the Members of IT-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, 1993). In addition, the World Telecommunication Standardization Conference (WTSC), which meets every four years, approves Recommendations submitted to it and establishes the study programme for
13、the following period. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication ad
14、ministration and a recognized operating agency. O ITU 1996 All rights reserved.

17、the Reversed Charge Supplementary Service over the ISDN. This service is defined in Recommendation 1.256.3 Calling Party Either Called Party Not Requested 1 General 1.1 The Reversed Charge Supplementary Service for the ISDN requires no Operator involvement and is not restricted to telephony. The ser
18、vice is defined with four cases each of which applies the Reversed Charge function differently. All service cases are established on the basis of bilateral agreement Table 1 summarizes the differences and highlights the functionality that has the most bearing on charging and accounting. Requested At

Charges for Case D should be on the basis of: a) b) invocation charges; or c Cases A through C all require the Called Party to acc

21、becomes responsible for the charges that are applicable to the related bearer service. For Cases A, C and D that responsibility applies to the entire call. For Case B the Calling Party has responsibility for the call charges up to the time of invocation. Beyond that time the charges are the responsi
22、bility of the Called Party. Table 2 describes those responsibilities: Recommendation D.233 (07196) I STD-ITU-T RECMN D-233-ENGL L99b 48b259L Ob2307b 545 Function Reverse Charge Requested By TABLE 2D.233 Case A Case B Case C Case D Calling Party Either Called Party Not Requested Call Set-up I Reverse

24、s as covered under Recommendation D.220 relates to calls Set-up and paid for by the Calling Party. The Reverse Charge Supplementary service requires that bearer service charges for Cases A and D be treated as those for calls originated by the Called Party and accounted for accordingly. Case B requir
25、es that the call up to the time of invocation be treated as a normal sent paid call while the call beyond the time of invocation be treated as a call originated by the Called Party. Accounting may therefore appear as related to two separate calls. Case C should be accounted for as a single call orig
26、inated by the Called Party. Bearer Usage after invocation Paid By 5 Interworking implications 5.1 The principles defined above apply to the Reversed Charge Supplementary Service in a total ISDN environment. The requirements to start and stop billing, collect data in a different form, perhaps retroac
27、tively, may not be supported across intenvorking interfaces. This aspect of the Reversed Charge Supplementary Service as well as the possible interaction of other Supplementary services with the related bearer service is therefore left for further study.
